Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Recently Adopted Accounting Standards In January 2017, the Financial Accounting Standards Board (FASB) issued an accounting standards update which clarifies the definition of a business. Under the new guidance, a set of integrated activities and assets is a business only if it has, at a minimum, an input and substantive process that together significantly contribute to the ability to create outputs. The update also introduces the concept of an initial screening or “Step 1” which requires companies to first determine if substantially all of the fair value of the gross assets acquired is concentrated in a single (or group of similar) identifiable assets. Transactions that pass the Step 1 screening will be considered a business if they contain an input and substantive process and either; (1) an output or (2) an organized workforce with skills critical to the ability to create outputs and inputs that can be utilized to create the outputs. Companies will no longer be required to evaluate whether a market participant could replace any missing inputs or processes, instead focusing on the substance of what was acquired. The provisions of the new standard are effective, on a prospective basis, beginning January 1, 2018, for annual and interim reporting periods and may be adopted early for any transactions not yet reported in issued financial statements. We elected to early adopt the new standard for any new transactions occurring on or after January 1, 2017. In July 2015, the FASB issued an accounting standards update to simplify the measurement of inventory by requiring that inventory be measured at the lower of cost or net realizable value, rather than at the lower of cost or market, with market being defined as either replacement cost, net realizable value or net realizable value less a normal profit margin. We adopted this guidance as of January 1, 2017. This guidance did not have a significant impact on our condensed consolidated financial statements. Recently Issued Accounting Standards In March 2017, the FASB issued an accounting standards update to simplify and improve the reporting of net periodic pension benefit cost by requiring only present service cost to be presented in the same line item as other current employee compensation costs while remaining components of net periodic benefit cost would be presented within Other (income)/deductions—net outside of operations. We plan to adopt this guidance as of January 1, 2018, the required effective date, and do not expect the new standard will have a significant impact on our consolidated financial statements. In October 2016, the FASB issued an accounting standards update that will require the recognition of the income tax consequences of an intra-entity asset transfer, other than inventory, when the transfer occurs as opposed to when the asset is sold to an outside third party. The provisions of the new standard are effective beginning January 1, 2018, for annual and interim reporting periods. Early adoption is permitted beginning on January 1, 2017. We plan to adopt this guidance as of January 1, 2018, the required effective date, and do not expect the new standard will have a significant impact on our consolidated financial statements. In February 2016, the FASB issued an accounting standards update which requires lessees to recognize most leases on the balance sheet with a corresponding right of use asset. Leases will be classified as financing or operating which will drive the expense recognition pattern. For lessees, the income statement presentation and expense recognition pattern for financing and operating leases is similar to the current model for capital and operating leases, respectively. Companies may elect to exclude short-term leases. The update also requires additional disclosures that will better enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. We plan to adopt this guidance as of January 1, 2019, the required effective date, for annual and interim reporting periods. The new standard requires a modified retrospective adoption approach, at the beginning of the earliest comparative period presented in the financial statements. We continue to assess the potential impact that adopting this new guidance will have on our consolidated financial statements. In May 2014, the FASB issued an accounting standards update that outlines a new, single comprehensive model for companies to use in accounting for revenue arising from contracts with customers. This update supersedes most current revenue recognition guidance under U.S. GAAP. The core principle of the new guidance is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance includes a five-step model for determining how, when and how much revenue should be recognized. This update also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. We plan to adopt this guidance as of January 1, 2018, the required effective date, using the modified retrospective transition method. Under the modified retrospective method, the cumulative effect of applying the new standard will be recognized as of the date of initial application with disclosure of results under both the new and prior standards. We continue to assess the impact of the new standard on our current policies and procedures related to revenue recognition. Based on the work performed to date, we do not believe that the adoption will have a material impact on our consolidated financial statements. While implementation procedures are still ongoing, we have evaluated the impact on our primary revenue stream, product sales, in both the United States and our key international markets and no matters have currently been identified individually or in the aggregate that would have a material impact on the timing or amount of revenue recognition based on the provisions of the new standard.
